Definition
The limit of a function is the value that the function approaches as the input approaches a certain value or infinity. It represents the behavior of the function near a specific point.
The derivative of a function represents its rate of change at any given point. It is closely related to limits and helps analyze functions in calculus.
Infinitesimal: An infinitesimal refers to an extremely small quantity that approaches zero but is not exactly zero. In calculus, limits are used to handle infinitesimals and understand their behavior.
